Abstract
Functional molecules derived from stereogenic phosphorus centers have important applications in the discovery of drugs and agrochemicals. They are also widely utilized as chiral ligands or organocatalysts for diverse asymmetric transformations. However, access to P-stereogenic motifs has always been regarded as a highly challenging yet desirable goal in organic synthesis. The development of general and practical methods for the stereoselective construction of synthetically versatile P(III)-stereogenic phosphines is particularly appealing but remains elusive. Herein, we describe a nickel-catalyzed asymmetric alkylation of primary phosphines with alkyl halides for the synthesis of P-stereogenic secondary phosphine-boranes with high enantioselectivity and broad substrate scope. The resulting optically active secondary phosphine-boranes allow for further stereospecific transformations, thereby establishing a modular and efficient platform for the diversity-oriented construction of P-stereogenic phosphine compounds.
